Spent a few hours trying to figure out how to display my own page in place of the default page for editor/submissionReview/1 but no success. Modified the code testing for values of $page and $op successfully, but not successful creating a variable to grab the "1" value. Also, studied similar code in dataverse and support group (http://pkp.sfu.ca/support/forum/viewtopic.php?f=9&t=7909) but so far haven't been able to work out the chain of events that results in a php page appearing in the browser. Specifically, exactly how to invoke the template file properly.
